Offering 32 percent more power and a 10 percent reduction in emissions over the previous model, the Santa Fe SUVs will go up against the likes of Holden's Sportwagon and Skoda's Superb in the 3000km trek from Darwin to Adelaide.
Held from the 24th to the 31st of October, the Global Green Challenge (formerly the World Solar Challenge) sees manufacturers, universities and private organisations from around the world facing off to prove - and improve - their latest advancements in alternative fuel and fuel-saving technologies.
Kevin McCann, Sales and Marketing Director of Hyundai Australia said no special tricks will be used in showing buyers the savings possible with the company's big all-wheel-drive seven-seat SUV.
"It will be a real world test - no wing mirrors folded flat or anything like that - and will show owners how much they can save in terms of both fuel costs and reduced emissions by driving the latest generation Santa Fe," Mr McCann said.
Hyundai's all-new 2.2 litre R turbo-diesel engine is an all-alloy unit that develops 147kW of power and peak torque of 422Nm, available between 1800rpm and 2500rpm.
In 2007, Hyundai took on the Panasonic World Solar Challenge - over the same Darwin to Adelaide route - and achieved a fuel economy of 3.2 l/100km in an i30 CRDi.
Hyundai is set to launch the updated Santa Fe next week, and TMR will be there to bring you full coverage and a 'first drive' review.
